Abstract

Two new selaginellin derivatives, selaginellins K (1) and L (2), were isolated from Selaginella tamariscina (Beauv.) Spring and characterized as 2-formyl-4,4′-dihydroxy-3-[(4-hydroxyphenyl)ethynyl]biphene and 4,4′-dihydroxy-2-methyl-3-[(4-hydroxyphenyl)ethynyl]biphene on the basis of their spectroscopic data including UV, IR, 1D, and 2D NMR as well as HR-ESI-MS spectroscopic analysis.
